Shigeru Miyamoto explains the making of Super Mario Bros.’ first level

It’s hard to overstate the importance of World 1-1, the first level in the original Super Mario Bros. It’s more than just the start of Nintendo’s most iconic game; it’s the start of modern video games as we know them. There’s a level of consideration for the player’s learning experience in its design that wasn’t really seen before Super Mario Bros. Compared to other games of the time, the journey that lay ahead of Mario was long and complicated, full of new ideas its audience needed to learn and experiment with. World 1-1’s blocks, goombas, pipes—all of them were carefully placed to guide us through that learning process, and developers have been following this template ever since.
